[Bug c++/13270] New: Failed compile of template function in template class called from another template

["Mark dot Hodson at dsto dot defence dot gov dot au" <gcc-bugzilla at gcc dot gnu dot org>]

G'day everyone, this bug is in v3.3.3 and v3.4 (20031126), though the error 
message it emits differs for the two.  My guess is you are most interested in 
the result for v3.4, thus I have logged this bug against that version.

It appears not to be related to any existing template bugs, though without good 
knowledge of the innards of GCC I may be wrong.  Furthermore, my guess for the 
component would either be c++ or libstdc++, but I have no idea which.

The short of it is that GCC accepts the source with VIA_FUNCTION_TEMPLATE and 
VIA_CLASS_TEMPLATE defines commented out - in this case the only Test template 
instantiation is from main(), which works fine.  With either macro uncommented, 
effectively the same code as is in main() is reproduced inside another template 
(either class or function), and an instance of this template created in main
().  Here GCC fails to compile with a rather uninteresting low-level-parse 
style error.  The test is as concise as I could get it, hope it helps.

Test system:
RedHat Linux 9, i386 build of GCC 3.3.3 GNU release packages (RPMs).
RedHat Linux 9, i686 bootstrap build of GCC 3.4 snapshot 20031126.

Test invocation:
g++ -g -Wall -c template_type_test.cpp -o template_type_test.o

Test output (v3.4):
template_type_test.cpp: In function `void TestSetF(const Allocator&)':
template_type_test.cpp:22: error: expected primary-expression
template_type_test.cpp: In static member function `static void 
TestSetC<Allocator>::DoIt(const Allocator&)':
template_type_test.cpp:36: error: expected primary-expression

Test output (v3.3.3):
template_type_test.cpp: In function `void TestSetF(const Allocator&)':
template_type_test.cpp:22: error: parse error before `>' token
template_type_test.cpp: In static member function `static void 
TestSetC<Allocator>::DoIt(const Allocator&)':
template_type_test.cpp:36: error: parse error before `;' token

This compiles successfully under both MS VC7.1 (.NET 2003) and Borland C++ 
Builder 6.  I will attach the source once I figure out how to use Bugzilla :).
